Wait, what are Refcardz?

We publish a new/updated peer-reviewed ~6pg reference card / cheat sheet every week. We've published 225 so far, not counting new versions that supersede the previous version (new Scrum Refcard supersedes the previous version; new Java EE 7 card doesn't, beause plenty of people still use EE 6). Every card is reviewed by two sets of peers: two or three representatives of the intended audience (experienced developers who aren't already expert in this particular technology) and two or three technical experts (who already specialize in the technology covered in the card).

Our goal for every Refcard is that -- once you've read it and every time you look back over it -- you'll be able to do something significant (related in software development) that you weren't able to do before. The mantra of the Refcardz series is: do something real.

What Refcards are you already planning to publish?

We've scoured out current Refcardz library, attended ~a dozen conferences, spoken with who-knows-how-many developers and executives, and assembled data from multiple Guide surveys to set a tentative publication calendar for 2016.
